After 2 days at 21°C, copper sulfate solution may undergo some changes due to exposure to air and light. The solution may start to oxidize, forming copper oxide or copper hydroxide precipitates. Additionally, some of the copper sulfate may decompose into copper oxide and sulfur trioxide. Overall, the solution may appear cloudy or have a slight color change due to these reactions taking place over time.

FranAt 21°C, copper sulfate solution will likely remain stable without significant changes in appearance or properties such as color or clarity over a 2-day period. However, some evaporation may occur, leading to a slightly higher concentration of copper sulfate in the solution.

How long does it take to grow copper sulphate crystals?
It typically takes 1-2 weeks to grow visible copper sulfate crystals in a saturated solution at room temperature. The size of the crystals and the conditions of the solution can affect the growth rate.
Describe how crystals of copper sulphate are prepared?
Copper sulfate crystals can be prepared by dissolving copper sulfate powder in warm water until it reaches saturation, then allowing the solution to cool slowly. As the solution cools, copper sulfate will start to crystalize out of the solution. The crystals can be left to dry and then harvested for use.
What changes would you observe if you leave a copper sulphate in a room at 21 degrees for 2 days with a lid on the top?
The water from the solution evaporates. A decrease at mass and volume would also occur.
What can copper sulphate do to a dish if you leave it in room temperature for two days?
If copper sulfate comes into contact with a dish left in room temperature, it may oxidize and form copper oxide, which can stain the dish. It is also toxic if ingested, so it is important to clean the dish thoroughly before further use. Additionally, copper sulfate can react with certain substances in the dish and affect the taste or safety of food prepared in it.
How can you filter water from copper sulfate when copper sulfate decomposes when during heating?
You can filter the water from copper sulfate by using a vacuum filtration setup that separates the solid copper sulfate particles from the liquid water. This method avoids the need to heat the copper sulfate, which can cause it to decompose.
